LANplex in a
Subnetted
Environment
The LANplex system allows you to fit Ethernet switching capability into
highly subnetted environments. When you put the LANplex system
into a subnetted network, it streamlines your network architecture and
easily switches traffic between and within subnets over Ethernet and
FDDI. See Figure 3-2.
